I've been having problems with my Intensity Pro for several months now. It was working fine back in August then BLAM! I stopped getting a preview screen. I've been through the process of sending it back to BlackmagicDesign, with them confirming my device was working fine for them. After searching around for a bit, I've found out that several users are having problems with the drivers 3.5 onwards - I was using 3.9.1.
So I've reinstalled the 3.4 driver and I'm now getting a preview screen, although there is still a problem! The preview screen and recordings are green and pink (see link below) and is also flickering. My HDMI cables are brand new and work with other appliances, so it isn't anything to do with them.
Does anybody have an idea how to fix this? Keep in mind that my card has been working from January 2010 till August 2010 without any problems, so my PC is able to handle it. I can post my PC specs if need be.
